SCOTTSDALE, Ariz. — After missing one day with back tightness, Giants center fielder Angel Pagan went through the full team workout Monday. When the Cactus League season kicks off Wednesday, however, the Giants still will be without their full complement of starters.

Manager Bruce Bochy already had announced that Yusmeiro Petit would start the opener because the regular rotation won’t start taking turns until after Thursday’s off day, and Bochy also has decided that Petit won’t throw to Buster Posey. The catcher will be held out as Bochy tries to find periodic spring breaks for the former MVP.

“He’s fine,” Bochy said. “It’s my call.”

The Giants also will be without Marco Scutaro, who remains on a light schedule as the staff eases him into things. Scutaro dealt with back trouble all of last season and has yet to participate in a team workout or take full swings in the cage.

While Scutaro has stayed on the back fields at Scottsdale Stadium, Posey, who put on 10 pounds of muscle in the offseason, has impressed. When the starters did baserunning drills Sunday, Posey appeared to be running better than he has at any point since 2011’s ankle surgery.

“I told him that,” Bochy said, smiling. “But let me add to that, let all those guys catch 100 games and you’ll see them slow down.”

Bochy revealed that Posey has always had the green light on the bases, although he rarely goes. Posey is just 6 for 10 in his career when attempting to steal a bag.

Major League Baseball’s new guidelines for home plate collisions were released as players were dressing and leaving the clubhouse. Posey briefly looked at the rule changes on a reporter’s phone but said he preferred to withhold any comments until after he had a chance to read the full release.

Infielder Tony Abreu disappointed a year ago because of knee injuries, but the veteran has looked spry and powerful.

“He’s moving so much better,” Bochy said. “He looks really good.”

Abreu had just 147 at-bats a year ago, hitting .268 with two homers. He is vying to make the club as a backup infielder.

Tuesday’s intrasquad game will feature some of the organization’s most exciting prospects. Right-hander Kyle Crick, the Giants’ top prospect, and left-hander Edwin Escobar, thought to be the one closest to the majors, will start the three-inning game.

Outfielders Gary Brown and Mac Williamson, infielder Joe Panik and catcher Andrew Susac are among the players who will get a shot to impress coaches. Management has said hard-throwing reliever Derek Law has a chance to make the team this spring, and Law will pitch an inning Tuesday.

Otto Warmbier was arrested in January 2016 at the end of a brief tourist visit to North Korea. He had been medically evacuated and was being treated at the University of Cincinnati Medical Center when he died at age 22.
